How To Get A Listbox To Update After The Add Method Is Called

Mar 10, 2010

I am having a problem with getting a listbox to update after the add method is called. I am using an AsyncFileUpload control and as part of the AsyncFileUpload1_UploadedComplete I am creating a listItem and then adding that to the listbox. The item will not appear in the listbox. I have tried putting the listbox in an update panel and then calling the Update method on the panel from within the AsyncFileUpload1_UploadedComplete procedure and that too fails to update the listbox. I can call the Update method on the panel from a separate procedure and still the listbox will not update with the item added in the AsyncFileUpload1_UploadedComplete method.

Controller Method Not Always Called From $.getJSON Request?

Mar 9, 2010

I have a controller method that returns a jSON object and in one calling situation, it works and in another calling situation, it does not work. When the URL in my browser is this:

http://localhost:65247/Client -- it works.

But, when my url looks like this:

http://localhost:65247/Client/UserAdmin?id=6 -- it DOES NOT work

In a nutshell, clients have users. From within the client, I wish to work on a specific user (this is the UserAdmin view). In this case, the client id is 6. From within the UserAdmin view that was launched with Id=6, I then wish to select a user from a dropdown. The idea was to use javascript and $.getJSON to fetch data for the specific user so as not to have to refresh the entire page. I use this approach in other parts of the app. The only difference I can see is with the URL in the browser. It would appear the presence of parameters via the '?' is futzing things up a bit.

MVC :: Initialize Method Called Multiple Times?

Jul 6, 2010

I'm overriding the Controller.Initialize method to set some stuff before each ActionResult is executed, however I'm finding that the method is being called multiple times for each request (anywhere between 2 - 10 times). I'm running in Cassini.

My hunch is that it is running for all static files (images, css etc) as well as the requested action - although I may be wrong? I thought maybe something was wrong in my web.config but it all looks right to me.

.net - MVC LinkButton Equalization - Overloaded Index() Method Isn't Called?

Feb 4, 2010

I'm rewriting a Web Forms application as an exercise to learn some MVC skills.I have a number of LinkButtons on the original application which postback and raise a serverside event that rebinds data to a datagrid.

Event handlers:
protected void lbtnOffset0_Click(object sender, EventArgs e)

What I currently have in MVC is this:

<%= Html.ActionLink("CurrentYr", "Index", 0)%>
<%= Html.ActionLink("1", "Index", 1)%>

public ActionResult Index()
return View(MietController.GetMietByYearOffset(0);

As the ActionLink renders an tag it doesn't postback so my overloaded Index() method isn't called. What are my options for doing this in MVC?

How Many Times Does HttpModule Init() Method Get Called During Application's Life

Jul 30, 2010

Web application initialization is as follows:

As we know when IIS receives the first request for a particular Asp.net application resource, IIS creates an instance of a HttpApplication (defined in global.asax codebehind).When this new instance is created it's initialization happens that also checks all configured HTTP modules.All modules are then instantiated and put in the application's Modules collection (of type HttpModuleCollection)modules are looped through and their Init() method is called (when they register for request events)

As far as I understand it the above scenario happens when a web application is started/initialized (hence application start event).What happens with modules?

Are they (re)instatiated on each request or reused from the Modules property on each consecutive request while the web application is alive? As I understand IIS and Asp.net they are reused through the whole life of a web application.

If they are reused, can we assume that their Init() method is actually a pseudo event handler for application start event? The thing is we can't attach to application level events within http modules. But if they are being reused we could use Init() as application start event and do whatever we'd put in global.asax instead.

Question,Can we assume that module's Init() method is called only on application start event? Could we use this assumption to i.e. register routes for applications whose global.asax codebehind we can't change? web.config is usually accessible and we can change it the way we want.Would this actually work?

Additional info,We can check HttpApplication code and check its InitModulesCommon() method. This one actually calls Init() of each registered HTTP module. What is more interesting is that this method is only used by InitIntegratedModules() and InitModules() methods. Which are both used only in HttpApplication.InitInternal() method. This is the basis of my assumptions, but I would like to know whether someone has abused IHttpModule.Init() for application start event.

MVC :: Can't Reach Controller - Javascript Library And Method Called From View

Jul 23, 2010

I have a javascript library and in there i have a method that is called from my view. Here it is:

<li><a href="javascript:void 0" onclick="deleteAll('image', '<%= ViewData["FileGroupId"]%>')"><div><%=GetGlobalResourceObject("default", "Delete_all") %></div><div></div></a></li>
and here is my js code in the javascript library:
var deleteAll = function(module, groupId) {
jConfirm(_deleteConfirmAll, _deleteAll, function(r) {
if (r) {
cache: false,
type: "POST",
url: _baseUrl + "/" + module + "/deleteall/" + groupId,
success: function(msg) {
if (msg == '0') {
location.href = _baseUrl + '/' + module;
else {
jAlert(msg, _errorTitle);
My problem is that i cant reach my controller. Here is my controller code:
#region common methods
List<.CMS.Core.File> GetList(int groupId)
List<CMS.Core.File> list = new List<CMS.Core.File>();
CMS.Core.FileFilter filter = new CMS.Core.FileFilter();
filter.GroupId = groupId;
int res = CMS.Core.File.Search(_connection, filter, ref list);
return list;
public ActionResult DeleteAll(int groupId)
List<CMS.Core.File> list = GetList(groupId);
foreach (File item in list)
return Json(list);
And at last her is my Index method
public ActionResult Index(int? id)
if (Request.IsAjaxRequest())
JsonPaging paging = new JsonPaging();
int offset = 0;
int page = 0;
if (!String.IsNullOrEmpty(Request.QueryString["page"]))
Int32.TryParse(Request.QueryString["page"], out page);
if (page > 0)
offset = (page * paging.PageSize) - paging.PageSize;
FileFilter filter = new FileFilter();
filter.Deleted = false;
filter.MaxRecords = paging.PageSize;
filter.Offset = offset;
if (!String.IsNullOrEmpty(Request.QueryString["keywords"]))
filter.FilterType = FilterTypes.AND;
filter.Name = Request.QueryString["keywords"].ToString();
if (!String.IsNullOrEmpty(Request.QueryString["sort"]))
filter.OrderBy = Request.QueryString["sort"].ToString();
if (!String.IsNullOrEmpty(Request.QueryString["direction"]))
filter.OrderBy = filter.OrderBy + " " + Request.QueryString["direction"].ToString();
if (id > 0)
filter.GroupId = id.Value;
List<CMS.Core.File> items = new List<CMS.Core.File>();
int results = CMS.Core.File.Search(_connection, filter, ref items);
foreach (CMS.Core.File current in items)
JsonItem item = new JsonItem();
item.Id = current.Id;
item.Name = current.Name;
item.ImageText = current.ImageText;
item.Aperture = current.Aperture;
item.TakenOn = current.TakenOn;
item.Camera = current.Camera;
item.ExposureTime = current.ExposureTime;
item.FocalLenght = current.FocalLenght;
item.Tags = current.Tags;
item.Url = current.Url;
item["Active"] = current.Active.ToString();
item["Created"] = current.Created.ToString();
return Json(paging, JsonRequestBehavior.AllowGet);
ViewData["FileGroupId"] = id;

How To Make Sure That CreateChildControls () Method Is Called When Unit Testing Custom .NET Web Controls

Feb 10, 2010

I want to unit test my rendering engine for an ASP.NET app. I have some custom controls created in that app. Most of those control rely on having CreateChildControls() method called by the ASP.Net engine wheather during initial call or a postback.When running a test CreateChildControls() does not get called and the control is in an "invalid" state.

As a workaround to get the tests going I explicitly call some other public method that calls EnsureChildControls() in it. This in effect causes CreateChildControls() to be executed and the control being initialized properly (just as it would normally when hosted on web server). I would like to get rid of that extra method call and the control to still be in a proper state for testing.

Webservice Doesn't Get Called By JQuery

May 25, 2010

I want to call a webservice using jQuery.ajax() but the webervice doesn't get called. - If I change the url: to reference a .ashx file it gets called but not .asmx?

Here's the code I'm using:

type: "POST",
url: "/services/CheckUsername.asmx/CheckUsername", // this doesn't get called
//url: "/services/CheckUsername.ashx/ProcessRequest", this gets called
data: '{ "context": "' + "username" + '"}',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (msg) {
alert("Result: " + msg);
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Error: " + textStatus)

The .ashx file gets called but a parsererror is retuned because it's returning http context - how can I modify this to get a string return type from a webservice?

.NET MVC Controller FileContent ActionResult Called From JQuery?

Feb 10, 2010

I have a controller method "SaveFile" that attempts to download a binary stream to client's PC using the FileContentResult. If I make the call as a post from the controller corresponding view everything works OK. I want to call the same controller method "SaveFile" from a jquery function via an .ajax call, when I do the function returns an error and the responseText is the contents of the file to be written. What would I have to do to get the same behavior from a jQuery function as if the MVC framework handled the call via the submit button? Or an alternate solution would be to determine how can I catch the browser's download dialog close event.
